Wind speed prediction method and related equipment

Abstract

The embodiment of the invention discloses a wind speed prediction method. The method comprises the steps of obtaining wind speed prediction data of a first region at different ground clearances; calculating a surface friction coefficient value corresponding to the first region by using the wind speed prediction data of the first region at different heights from the ground; obtaining the average altitude of the first area; obtaining an average altitude of a second area, wherein the second area is located in the first area; and substituting the wind speed prediction data corresponding to the first area, the average altitude of the first area, the average altitude of the second area and the surface friction coefficient value into an index formula to calculate the wind speed prediction data corresponding to the second area.

Description

technical field [0001] The embodiments of the present application relate to the field of natural environment, and in particular, to a wind speed prediction method and related equipment. Background technique [0002] Wind speed refers to the speed of air movement relative to a fixed location on the earth. The common unit is meter per second. Wind speed is the basis for the division of wind power. Generally speaking, the higher the wind speed, the higher the wind level, and the more destructive the wind. Wind speed is one of the main parameters in climatology research, and the measurement of atmospheric wind plays an important role and significance in global climate change research, aerospace industry and military applications. Therefore, predicting wind speed is an important means to prevent natural disasters and improve disaster resistance. There are various and more accurate methods for wind speed prediction in large areas. Generally, predictions can be made based on var...
